WHEELS ARROW-Flhki/EE Application filed July 3, 1907.

Specification of Letters Patent.

T 0 all whom it may concern: I

Be it known that l, FRANK J. Coornn, a citizen of the United States, rr-rsiding at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useiul linproven'ients in Wheelbarrow-Frames and I do declare the following to a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to wheelbarrowfran'ies and its obj .ct is to provide a con.- struction which shall be cheap, siinp and strong and wl'iich shall provide for assembling of the parts,including the securing of the tray pon tho fraine with a minimum number of parts. I attain these objects by means of the devices and arrangement of parts hereinafter described and shown, and illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of my frame with the legs and tray removed; Fig. 2, a central longitudinal sectional elevation. of the same with the tray in place; F 3, a side-elevation showing the arrangement of the legs and leg-braces hereinafter referred to, and Fig. d, a transverse sectional elevation of the same taken on line ma: l ig.

In the drawings, in which like numerals of reference indicate like parts, 11 are the side-bars or handle-bars of my barrow, having handles at one end and converging toward the other end where the bars are provided with bearings 2 for the wheel,-these bearings being of the usual or of any preferred form.

33 are cross-braces which connect the side-bars, the two braces being disposed in the same plane with the side-bars and so arranged that they form supports for the front part and the rear part of the wheelbarrow-tray 4. The braces 3 are composed of angle-iron substantially L-shaped in transverse section. Each brace 3 at each end is split longitudinally for a short distance along the meeting line of the two members of the angle-bars. The vertical separated portions of the angle-bars are bent at such an angle as to conform to the converging lines 1 le 1" 7 one of the hai'idle-bars, at 5, leaving the soparated portions of the other ineinb "s of the angle-bars undisturbed. The fiat unbont projecting portions of the angle-bars 3 rest on. the top of the side-bars, as at 6, while the separated bent portions 5 of the angle-bars fit snugly against the inner sides of the sidebars. The parts 5 are pierced for the reception of bolts 7 vhich pass horizontally through the side-bars and through the parts 5, the bolts being secured in place by nuts 8. The parts of the anglebars which overlap the tops of the side-bars are also pierced for the reception of bolts 9 which pass vertically hrough the side-bars and through the bottom of the tray 4. Upon the bolt 9 are nuts 10 by means of which the side-bars, the crossbraces, and the tray are rigidly secured together in fixed relation. The bolts 9 may be inserted either from above or below as illustrated in the drawings.

ll ll are two pieces of anglobar substantially like the pieces 3 3, above mentioned, in transverse section. These pieces are bent into irre ular U-shape, as shown, and at both ends are or a short distance split along the line of their angle.

I One of the separated portions at the forward end of each. of the parts 1] remains intact, at 12, the other separated portion, 13, being bent at an angle, the portions 12 resting against the outer side of the side-bars 1, the portions resting against the underside of the handlebars, the bent angl' bars thus forming le 7 i'or the barrow. The two legs, near the ground, are connected by a (-,ross-bracc 14 formed of a strip of angle-iron corresponding in cross-section with the pieces above described and having its extremities disposed in the inner angles of the leg-pieces as shown in Fig. L. The ends of the cross-braces 14 are secured to the leg-pieces by bolts 15 passing through their contacting flat parts.

16 is a brace or truss composed of llatbariron bent in d-shape and resting at its angle upon the horizontal web of the brace 1% midway of its length. fit this point the parts 14 and 16 are rigidly secured together by means of bolt and nut 17. it its upper ends the part 16 is bent horizontally. hrough these horizontal portions of the part 16 and through the horizontal split portions of the legs are holes which coincide with and receive the vertical bolts 9 so that the sidebars, the

upper cross-braces, the le s, the truss 16, and the tray are all engaged and secured. in fixed relation by the two nuts and bolts 9. The vertical split portions of the legs resting against the outer side of the side-bars have holes which coincide with and receive the bolts 7 so that these bolts horizontally engage the cross-braces 3, handlebars 1, and legs 11. 'l he rear ends of the leg-pieces,the ends next the wheel,-are secured to the under side oi the side-bars by means of the bolts 9 which pass vertically through the tray the rear cross-brace and the rear end of the leg.

'lhus it will be seen that the side bars, the I cross-bars, the legs, the cross-brace for the legs, the truss, and the tray are all rigidly secured together in fixed relation with a minimum number of bolts and nuts, and thatby the construction shown great rigidity and strength in proportion to weight are obtained.

raving described my invention, what I claim and desire to secure by Letters Patent is,

1. In a wheelbarrow-frame, a pair oi sidebars, a pair of horizontal cross-braces, one in advance of the other, said. cross-braces comprising angle-bars substantially L-shaped in crosssection, the extremities of the anglebars being split on the meeting line 01' their two members, the vertical split portions being bent at an angle to fit the inner sides of the side-bars, the horizontal split portions resting on top of the side-bars, and bolts which engage the split portions of the en..- treniities of the cross-braces with the sidebars.

2. In a device of the described character, a pair of side-bars, a pair or" crossbra .'es between the side-bars said cross-braces being composed of angle-bars split at both ends on the line of their meeting angle, one of each pair of the split portions being bent horizontally to {it the inner side of the adjacent sidebar, the other split portion of each pair resting on the top of such. side-bar, a tray resting upon the frame thus formed, bolts which engage the bent members of the cross-braces with the sides of the sidebars, and bolts which connect the tray the side-bars and the unbent members of the cross-braces rigidly in fixed relation.

In a device of the described character, a pair 01' side-bars, a pair of legs composed of angle-irons substantially L-shaped in transverse section and bent in irregular U-shape, the forward ends of the respective legs being split on the line of their angle, one split por tion resting against the outer side of the sidebar the other split portion being bent to fit the under side of the sidebar, a tray, a crossbrace, bolts which respectively engage vertically the tray the cross-brace a side-bar and a leg, and bolts which respectively engage horizontally a leg a side-bar and a cross-brace.

4. In a device of the described character, a pair of side-bars, a pair of legs composed of angle-bars bent into irregularUshaped form and. secured at their opposite ends to the sidebars, a leg-brace which connects the legs near the ground, a truss connected centrally with the leg-brace and at its ends with the sidebars, a cross brace connecting the handlebars, a tray, and bolts which respectively enthe tray the cross-brace a side-bar a leg and the truss.

S. In a device of the described character, a pair or converging side-bars, a pair oihorizontal braces which connect the side-bars and which consist of angle-bars l..shaped in cross-section and split at their extremities on the line of their angle, said split portions being engaged with the top and inner sides of the side-bars, a pair of legs consisting of angle-bars t-shaped in. cross-section, split at their extremities on the line of their angle and bent into irregular U-shaped form the split portions ofsaid legs being engaged with the bottom and outer sides of the sidebars, bolts which engage res )ectively the split members on the top and ottoin of the sidebars, and bolts which engage respectively the split members on the inner and outer sides of the side-bars.

ln testimony whereof I allix. my signature in presence of two witnesses.
